HENRY W. ROBBINS, OF MEDINA, NEW YORK.

HINGE-JOINT FOR WIND-SHIELDS.

Application filed April 1, 1912. Serial No. 687,716..

T all whom it may concern:

Be it known that I, HENRY W. ROBBINS, a

' citizenof the United States, residing at Medina, in the county of Orleans and State of New York,'have invented anew and useful Improvement in Hinge-Joints for Wind- Shields, of which the following is a specification.

This invention relates more particularly to hin e 'joints for wind shields or glass fronts or automobiles in which the shield or a portion thereof is adjustable to different positions relative to its support or the remainder of the shield, but the invention is not limited in its use to wind shields and may be employed for various other purposes in which it is desired to hinge two parts together so that they can be adjustably secured in various positions relative to each other. a

One object of this invention is to provide a simple and economical hinge joint for this purpose which willjpermit the parts connected thereby to be easily adjusted to' dif ferent positions relative to each other and will hold the parts securely and firmly in their various adjusted positions.

A further object'of this invention is to provide a hinge joint of this type having an adjustable stop for limiting the extent to which the engaging portions of the joint can be released, so that there will besufiicient engagement between these portions when released to hold the parts from turning until some force is applied to them.

In the accompanying drawings: Figure 1 is a fragmentary side elevation of a wind shield provided with a hinge joint embodying the invention. Fig. 2 is an end elevation thereof. Fig. 3 is a cross-section thereof, onian enlarged scale, in line 3-3, Fig. 2. Fig. 4 is a section thereof, on an enlarged scale, in line 4-4, Fig. 1.

Like reference characters refer to like parts in the several figures.

The hinge joint comprises two members A and B, the member A having a circumferential tapered groove 0. and the member B having a tapered ring I) which is located in this groove and is adapted to turn therein for permitting the members to be ad usted relative to-each other and to be wedged or- .olan ped therein for holding the members Specification of Letters Patent.

from relative movement in their adjusted positlons.

For producing a wedging or clamping engagement between the ring b and the tapering sides'of the groove a, any suitable means may be employed. In the construction shown, the ring is split are and a screw threaded post is provided which is secured to one end of the split ring and extends through an opening 'in' the other end thereof and is provided at its'outer end with a thumb nut C. By turning this nut the split ends of the ring can be drawn'together, thus contracting the ring and causing it to wedge in the tapered groove a for clamping the members together. When the nut Cis released, the ends of the ring will separate, permitting the ring to expand so that one member can be turned relativeto the other.

To limit the expansionofthe split ring when the thumb nut is released, a suitable adjustable stop is preferably provided which, in the construction shown, consists of a screw D which is loosely mounted in one end of the split ring and has screw-threaded engagement with the other end thereof. By adjusting this screw the distance to which the ends will separate under the expansion action of the ring may be limited as desired. This permits the ring to 'be'released sufficiently so that the members of the joint may be turned relatively to" each other by hand but can not turn or shift their relative position of their own accord. v This is of especial advantage in wind shields where the hinged joints are arranged at each end of theshield and it is necessary to release both joints before adjusting the movable part of the shield.

The member A preferabl consists of a fixed part a and an adjustab e part (p 1; The

fixed part carries oneof the inclined'faces which form the tapered groove (1 and the adengage a shoulder formed on the part a at the inner end of the enlarged opening a and holds the part (I in position on the shank a. By turning this nut, the part a can be adjusted relative to the part a. for regulating the size of the tapered groove (1 to lit the tapered ring 7) and to take up w an on the engaging faces of the groove. A jam nut a on the outer end of the post a closes the opening 0.

if it is desired to disconnect the two members of the joint. this can be readily done by unscrewing the jam nut 11* and the adjusting nut u and taking off the part The split ring I can then he removed. By arranging the ring I) in the groove (1. the ring has but a very limited lateral movement relative to the member A even when released and the two members of the joint are at all times held in substantial alinement with each other.

"lhe two members of the joint may be secured to the parts which are to be con-- nected'thereby in-any suitable manner. In the construction shown. the member has a channel portion E which is preferably formed integral with the part (1' and emb aces and is secured to the end of the usual wooden dash or shield base l. and the member li is formed integ ad with the end of a rod (1 which *arries a glass shield ll which is secured thereto by suitable means (not shown). Similar connections are employed for the other end of the shield.

The employment of tapered engaging parts between the two members of the joint att'ords a gr atly incrased area of engaging surface between them withont materially increasing the size or width of the joint. and the .wedging action produced when these tapered parts are drawn together enables the two memhersof the joint to be securely and firmly clamped or forced together so that relative movement thereof is pl'mtically impossible until the members are released. The clamping or binding action is such that the joints will not work loose or become released under the constant jar and vibration to which they are subjected when used on wind shields. and the parts of the shield connected thereby an thus be securely retained in their adjusted position. The joint is simple and cconomi al in construction. can be easily assemblcd.-and readily manipulated for securing the parts connected thereby in different adjusted positions.
